Description

Technical Field

[0001] The utility model relates to a backlight display module, in particular to a backlight display module with anti-collision at the corners. Background Art

[0002] The TFT liquid crystal screen contains many precision components, such as a liquid crystal layer, a polarizer, a circuit board, etc. During the assembly process of the liquid crystal main screen and the backlight, the corners of the TFT liquid crystal glass may be impacted, thus affecting the normal operation of the liquid crystal main screen. When the impact occurs at the corners, since the structures in these areas are relatively fragile and more likely to be damaged, it may cause problems such as color distortion, uneven brightness, screen flicker or blurring in the display effect of the liquid crystal screen. If the impact force is large enough, it may even directly cause the liquid crystal screen to crack or shatter. In the prior art, for the anti-collision of the corners of the TFT liquid crystal screen, there are those that avoid it by fixing with specific jigs, and there are also those that limit and fix by adding other components or structures, and the operation and production are relatively cumbersome. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a backlight module with an inwardly retracted design at the corners of the iron frame, so as to achieve the purpose of avoiding the impact damage of the corners of the TFT liquid crystal glass during the assembly process.

[0005] A backlight display module with inwardly retracted corners of the iron frame, including a liquid crystal screen, a backlight and an iron frame. The liquid crystal screen and the backlight are mutually adhered. The iron frame tightly wraps around the four sides of the liquid crystal screen. The iron frame is fixedly connected to the side of the backlight away from the liquid crystal screen. Each of the four inner corners of the iron frame is provided with an inwardly retracted groove that retracts away from the liquid crystal screen. In this way, during the assembly process, if a collision occurs, the corners of the liquid crystal screen are limited by the inwardly retracted grooves and will not directly impact the corners of the iron frame, and the impact force is buffered, thereby being able to avoid damage to the corners.

[0006] Furthermore, the inwardly retracted groove includes a groove part and a beveled joint part adjacent to the groove part. The groove part is arranged in the direction away from the corners of the liquid crystal screen, and the beveled joint part connects the adjacent sides of the iron frame at the corner where the inwardly retracted groove is located.

[0007] Preferably, the connecting part of the beveled joint part and the adjacent side of the corner where the inwardly retracted groove is located is designed as a rounded corner.

[0008] Preferably, a flexible pad is attached to the inwardly retracted groove.

[0009] Furthermore, elastic stoppers for preventing the movement of the liquid crystal screen are provided on the four peripheral frames of the iron frame.

[0010] Preferably, the liquid crystal screen is covered with a protective glass having scratch and impact resistance.

[0011] Furthermore, one side of the iron frame is provided with an avoidance position for the FPC that is bent and attached to the backlight.

[0012] Furthermore, the iron frame and the backlight are provided with a mutually cooperating engaging structure.

[0018] In order to facilitate the understanding of the present utility model, the following will describe the present utility model more comprehensively with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present utility model more thorough and comprehensive.

[0019] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present simultaneously.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] The utility model provides a backlight display module with inwardly retracted corners of an iron frame, thereby avoiding the problem of corner impact damage during assembly of the backlight display module. Figure 1 , Figure 2 An embodiment of the invention comprises a backlight display module, comprising a liquid crystal screen 1, a backlight 2 and an iron frame 3. The liquid crystal screen 1 and the backlight 2 fit each other, and the liquid crystal screen 1 is tightly connected to the iron frame 3 on all sides. After assembly, the iron frame 3 is fixedly connected to a side of the backlight 2 away from the liquid crystal screen, and each of the four inner corners of the iron frame 3 is provided with an inwardly contracted groove 31 which is contracted inwardly in a direction away from the liquid crystal screen 1.

[0022] The design of this embodiment ensures that if a collision occurs during the assembly process, since the retracted groove 31 of the iron frame 3 retracts inward away from the liquid crystal screen 1, the corners of the liquid crystal screen 1 are restricted by the edge of the screen and will not collide with the four corners of the iron frame 3. The impact force is buffered, thereby avoiding damage to the corners.

[0023] In this embodiment, the inner contraction groove 31 includes a groove portion 311 and a bevel portion 312 adjacent to the groove portion 311. The groove portion 311 is arranged in a direction away from the corner of the liquid crystal screen 1, and the bevel portion 312 connects the adjacent sides of the iron frame 3 at the corner where the inner contraction groove 31 is located. When the liquid crystal screen 1 collides, the bevel portion 312 can first limit and fix the corner of the liquid crystal screen 1 to prevent the corner from directly rushing into the groove portion 311 when the liquid crystal screen 1 is subjected to a large force.

[0024] In another embodiment, the connecting part between the beveled portion 312 and the adjacent edge of the corner where the inner contraction groove 31 is located can be designed as a rounded corner, and the inner contraction groove 31 is attached with a flexible pad to further cushion the corners of the LCD screen that is impacted and moved.

[0025] In this embodiment, elastic stoppers may be provided on the four sides of the iron frame 3 to prevent the LCD screen 1 from moving, thereby fixing and protecting the edge of the LCD screen 1 when it is hit, and further preventing the LCD screen 1 from hitting the corners due to movement.

[0026] In the preferred solution of the first embodiment, the liquid crystal screen 1 is covered with a protective glass having scratch and impact resistance.

[0027] In this embodiment, one side of the iron frame 3 is provided with an escape position for bending the FPC 4 attached to the backlight 2, and the iron frame 3 and the backlight 2 are connected and fixed by a mutually matching snap-fit structure.

[0028] In this embodiment, the iron frame 3 is made of stainless steel or light alloy, and the iron frame 3 is not easily deformed.

[0029] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, combinations of solutions, several deformations and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
